They have been rolling out ad-blocker detection with warning popups telling you to disable it. Mine were skippable the first few times but that lead to a final 3 warnings with the player refusing to load after. They seem to be doing a lot of A/B testing with the system currently.
No don't do that. And stop spreading misinformation. There is a thread on Reddit explaining why this is absolutely stupid and will only result in you losing access to YouTube. Or do you really think YouTubes for works like this.
How would one lose access? Is Youtube blocking IP addresses? Fingerprinting browsers in a way that Firefox's ResistFingerprinting setting doesn't handle?
How is that misinformation?
The site you linked even says it works, just not for long an maybe with negative side effects:
> I was able to hide the popup simply by blocking it with uBO's Picker. Why aren't you doing that?
> This only works temporarily. For stages 1-3. You're still reach stage 4 by doing this. And this might cause scrolling issues and not let videos autoplay.
Maybe you should stop using words as "absolutely stupid" because it makes you look like a snob, and when it turns out you were wrong, it makes you look like a fool.
